1. What is the scientific name for the kneecap?

• A. Patella
• B. Femur
• C. Tibia
• D. Fibula

Correct answer: A

Rationale: The patella, commonly known as the kneecap, is a small, flat, triangular bone that sits at the front of the knee joint. It protects the joint from impact and helps to transmit force from the quadriceps muscle to the tibia (shinbone).

2. Which hormone, produced by the thyroid gland, regulates calcium levels in the blood by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys?

• A. Calcitonin
• B. Parathyroid hormone (PTH)
• C. Thyroxine
• D. Insulin

Correct answer: a

Rationale: The correct answer is A: Calcitonin. Calcitonin is a hormone produced by the thyroid gland that plays a crucial role in regulating calcium levels in the blood. It works by enhancing calcium absorption in the intestines and reducing calcium loss in the kidneys. This helps to maintain the proper balance of calcium in the body. Parathyroid hormone (PTH) works in the opposite way, increasing calcium levels in the blood when they are low. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism and growth, not calcium levels. Insulin is a hormone produced by the pancreas that regulates blood sugar levels, not calcium levels. Therefore, the correct hormone in this case is Calcitonin.

3. What is the difference between constructive and destructive interference of waves?

• A. They have the same effect on wave amplitude.
• B. Constructive interference increases amplitude, while destructive interference decreases it.
• C. They only affect light waves, not sound waves.
• D. They depend on wave speed, not amplitude.

Correct answer: B

Rationale: Constructive interference occurs when peaks of two waves overlap, resulting in a higher combined amplitude. Destructive interference happens when peaks and troughs overlap, cancelling each other out and reducing the overall amplitude.

4. The author expresses concern about the...

• A. high cost and limited efficiency of traditional fossil fuel power plants.
• B. unpredictable weather patterns and their impact on renewable energy production.
• C. increasing dependence on technology and potential cybersecurity risks.
• D. negative environmental consequences of renewable energy infrastructure.

Correct answer: B

Rationale: The passage's focus on managing the intermittency of renewable energy due to weather conditions implies concern about B.

5. Which sentence avoids a comma splice?

• A. The wind howled, the branches swayed, and rain lashed against the windows.
• B. He packed his bags, he checked the weather forecast, and then hit the road.
• C. The movie was entertaining, it was also thought-provoking.
• D. Tired and hungry, she stopped for a quick bite at the cafe.

Correct answer: C

Rationale: Option C uses a semicolon to separate two independent clauses, avoiding a comma splice.

6. How does the mass of an object affect its inertia?

• A. Mass has no impact on inertia
• B. Higher mass increases inertia
• C. Higher mass decreases inertia
• D. Mass influences gravitational force, not inertia

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This is in line with Newton's first law of motion, which states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.
